------------------------------------
Summary: Reconsider the best way to encode postings now that we
can skip non-competitive hits
Key: LUCENE-8760
URL: https://issues.apache.org/jira/browse/LUCENE-8760
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
The fact that we now skip non competitive hits has some implications to our
postings:
- we are now more likely to call advance vs. nextDoc
- we are less likely to read term frequency for a given doc, since we only do
that if the maximum score reported by impacts is competitive
- we are less likely to read positions for a given doc, since exact phrase
queries first check the maximum score that would be obtained with a phrase freq
equal to the minimum of all term freqs
It might be a good opportunity to re-explore the best way to encode postings.
